␥-Filamin, also called ABP-L, is a filamin isoform that is specifically expressed in striated muscles , where it is predominantly localized in myofibrillar Z-discs. A minor fraction of the protein shows subsar-colemmal localization. Although ␥-filamin has the same overall structure as the two other known isoforms, it is the only isoform that carries a(More)
gamma-Filamin, also called ABP-L, is a filamin isoform that is specifically expressed in striated muscles, where it is predominantly localized in myofibrillar Z-discs. A minor fraction of the protein shows subsarcolemmal localization. Although gamma-filamin has the same overall structure as the two other known isoforms, it is the only isoform that carries a(More)
The Rho GTPases are influential regulators of signalling pathways that control vital cellular processes such as cytoskeletal dynamics, gene transcription, cell cycle progression and cell transformation. A vast majority of the studies involving Rho GTPases have been focused to the famous triad, Cdc42, Rac1 and RhoA, but this protein family actually harbours(More)
Xin is a protein that is expressed during early developmental stages of cardiac and skeletal muscles. Immunolocalization studies indicated a peripheral localization in embryonic mouse heart, where Xin localizes with beta-catenin and N-cadherin. In adult tissues, Xin is found primarily in the intercalated discs of cardiomyocytes and the myotendinous(More)
The atypical Rho GTPase Wrch-1 has been proposed roles in cell migration, focal adhesion dissolution, stress fibre break down and tight junction heterogeneity. A screen for Wrch-1 binding-partners identified the novel RhoGAP protein, ARHGAP30, as a Wrch-1 interactor. ARHGAP30 is related to the Cdc42- and Rac1-specific RhoGAP CdGAP, which was likewise found(More)
Plectin is a high molecular mass protein (ca 530 kDa) that binds actin, intermediate filaments, and microtubules. Mutations of the human plectin gene cause epidermolysis bullosa simplex with muscular dystrophy. In mature human skeletal muscle, plectin is localized between neighboring myofibrils and between myofibrils and the sarcolemma, both at the level of(More)
BACKGROUND Mutations in the GJB2 gene, which encodes the Connexin26 (Cx26) protein, are the most common cause of childhood hearing loss in American and European populations. The cochlea contains a gap junction (GJ) network in the sensory epithelium and two connective tissue networks in the lateral wall and spiral limbus. The syncytia contain the GJ proteins(More)
